* Libbe is not available when cross-building the *_bootstrap packages,
so no libnetwork could not be used either, which made building
anything network-related impossible.
* The only code in libnetwork that requires libbe is the notification,
so I moved that over to libbnetapi. Non-C++ applications can't use
the notification calls anyway, as their interface is C++-only.
* The rounding algorithm here expects to start with the 2 digits
after the decimal point in pll->feedbackDivFrac. Multiplying with
1000 instead of 100 filled it with 3 digits.
The last step then set the fractional part to zero because it was
still too large.
Unfortunately OpenGL screen saver previews draw on top of the tabview,
so, when you switch to the General tab we now stop the screen saver
and then restart it when you come back to the Screensavers tab.
* Update the Doxyfile for 1.7.6.1. Doxywizard reformatted the comments; that's why this change is so big
* Disable graph inheritance trees; use "Inherits/Inherited by" lists instead (Doxygen has this on by default; I don't think it was intentional)
* Shorten two subgroup names; helps with formatting in Doxygen 1.8 and looks cleaner
* Moves the page footer ("The Haiku Book pre-R1...") be in a <footer> tag, and add a CSS rule for this tag
* Disable XML output, no one is using it
* Disable Microsoft IDL parsing, speeds up Doxygen a bit
The main purpose of using atomic_get() was the necessity of a compiler
barrier to prevent the compiler from optimizing busy loops. However,
each such loop contains in its body at least one statement that acts
as a compiler barrier (namely, cpu_wait() or cpu_pause()) making
atomic_get() redundant (well, atomic_get() is stronger - it also issues
a load barrier but in these particular cases we do not need it).
If the initial attempt to acquire read spinlock fails we use more relaxed
loop (which doesn't require CPU to lock the bus). However, check in that
loop, incorrectly, didn't allow a lock to be acquired when there was at
least one other reader.
* DrawPolygon was offsetting coords to pixel centers
regardless of whether the polygon was stroked or
filled, leading to wrong results for filling. Now
it offsets for stroking only and even takes pen-size
into acount. The bug was visible in Gobe Productive's
selection rendering.
* Renamed _Transform() methods to _Align(), which fits
better with what they do: Align coordinates with the
pixel grid.
* Changed rounding behavior for StrokeLine. Offsetting
to pixel centers depending on pen-size happens regardless
of sub-pixel mode. This means a stroked line on integer
coordinates looks the same in both modes. It breaks
some drawing in WonderBrush (brush cursor), which was
exploiting the previous behavior, but unbreaks Gobe
Productive caret rendering at zoom levels below 150%.
Both changes bring Gobe Productive text editing to a useable
level.
* The AMD-part of the add-on is supposed to reject some very old
models. However, a bug in the selection code caused it to reject
anything with model-number smaller 9 regardless of model-family.
This caused MTRR setup to not happen on many AMD CPUs and Haiku
being very slow on these machines.
* Fixes#10571
* Add isb just because.
* pdziepak pointed out that ARMv5 and before
had different barrier support.
* pdziepak also mentioned that dsb was too strong
for __sync_synchronize
* On ARMv6 or older, we do a simulated dsb.
* Move __sync_synchronize into thread.c in libroot
and use the new arch_atomic.h dsb/dmb defines.
* Gets arm @bootstrap-raw to end of bootstrap.
Since fonts are cached with a precision of one digit after the decimal point
for the font size, the char spacing values needs to be more precise. They are
now in font face units and scaled by the font size during layout. This yields
the expected results of the text positioning scaling smoothly along the base
line, even though the actual (hinted) glyph shape does not change with each
small change of the scale (or font size).
It doesn't yield quiet the expected results, yet. When hinting is turned on,
FontEngine takes a measurement of the precise advance values for each
cached glyph by invoking FT_Load_Glyph() with the FT_LOAD_NO_HINTING flag,
before loading the glyph for real without that flag. In GlyphLayoutEngine.h,
the precise advance value is used for B_CHAR_SPACING. The intended result
is that glyphs are rendered hinted (according to global Appearance settings),
but spaced along the base-line with precise, unhinted advance values. An
application would use this for example to implement precise page or print
preview and also for zooming text without altering the placement of glyphs.
For Gobe Productive, problems can be observed, because we don't implement this
correctly, yet.
* The code path actually used when the client uses BView::SetFont()
is DrawState::ReadFontFromLink(), where it forgot to a) adopt the
original font size in fUnscaledFontSize and b) scale the font by the
current combined scale. Fixes remaining part of #10578.
* Change default spacing to B_BITMAP_SPACING. The BeBook does not document
what the default spacing is, and I have no BeOS install handy to check.
However, I believe that B_BITMAP_SPACING is what should be the default,
since it gives the best visible result for the common use-case.
In terms of implementation, there is no change, since spacing was ignored
until now and the behavior was that of B_BITMAP_SPACING. This change could
however break BeOS apps which assume B_CHAR_SPACING is the default and don't
set it on new when they need it. Sample code in the BeBook however shows
setting B_CHAR_SPACING on a newly created BFont.
* Implement B_STRING_SPACING to do something sensible. The BeBook documentation
is completely vague in what it is actually supposed to do. Given the
possibilities of FreeType, I am implementing it to enable the use of
kerning. Kerning optimizes the spacing between two glyphs, for example, it
would decrease the spacing between "T" and "e" in the string "Test" for
our default font. Untested.
* Unify asterisk style
* switch indentation style of FontList declaration
* Order FontList methods according to declaration
* Use named constants in default BFont constructor for spacing and encoding.
